Dear Shareholder:

      You are cordially invited to attend the annual meeting of ONEOK, Inc. at

possible at the meeting. The matters to be voted on at the meeting are stated
in the Notice of Annual Meeting of Shareholders and are described in the Proxy
Statement. A report on the operations of ONEOK, Inc. will be presented.

      We know that most of our shareholders are unable personally to attend the
annual meeting. Therefore, proxies are solicited so that each shareholder has
an opportunity to vote by proxy. You can authorize a proxy by signing, dating,
and returning the enclosed proxy card. Shareholders whose stock is registered
in their name may also authorize a proxy by telephone or over the Internet.
Instructions for using these convenient services are set forth with this Proxy
Statement and on the proxy card. I urge you to submit your proxy as soon as
possible so that you can be sure your shares will be voted.

      Regardless of the number of shares you own, your vote is important. Thank
you for your continued interest in ONEOK, Inc.

Very truly yours,

                                Proxy Statement

The approximate date of the mailing of this Proxy Statement and proxy card is
April 10, 2002. This solicitation of proxies is being made by the Board of
Directors of ONEOK, Inc.

Quorum and voting

Record Date. The record date for the meeting is March 18, 2002. Only
shareholders of record at the close of business on that date are entitled to
notice of, and to vote at, the meeting.

Voting Stock. The only class of stock entitled to be voted at the meeting is
ONEOK's common stock. At the close of business on the record date, there were
60,259,570 shares of common stock outstanding and entitled to be voted at the
meeting, and the holders of those shares will be entitled to one vote per share.

Quorum and Votes Required. A quorum is a majority of the outstanding shares,
which may be present at the meeting or represented by proxy. There must be a
quorum for the meeting to be held. Directors are elected by a plurality of the
shares voted. Proposal #2 must receive the affirmative vote of a majority of
the shares present in person or by proxy to be adopted. If you appoint a proxy,
even if you abstain from voting, you will be considered part of the quorum.

Adjourned Meeting. If a quorum is not present at the scheduled time of the
meeting, the shareholders who are represented may adjourn the meeting until a
quorum is present. If the time and place of the adjourned meeting are announced
at the time the adjournment is taken, no other notice will be given. If the
adjournment is for more than thirty (30) days, or if a new record date is set
for the adjourned meeting, a notice will be given to each shareholder of record
entitled to vote at the meeting. An adjournment will have no effect on the
business that may be conducted at the meeting.

Voting of Shares Held in Street Name by Your Broker. Brokerage firms have
authority under New York Stock Exchange Rules to vote customers' unvoted shares
on certain "routine" matters, including the election of directors. If you do
not appoint a proxy to vote your shares, your brokerage firm may either vote
your shares on routine matters or leave your shares unvoted. We encourage you
to provide instructions to your brokerage firm by appointing a proxy to vote
your shares. This ensures your shares will be voted at the meeting. When a
brokerage firm votes its customers' unvoted shares on routine matters, these
shares are counted for purposes of the vote and for purposes of establishing a
quorum to conduct business at the meeting. A brokerage firm, however, cannot
vote customers' shares on non-routine matters. Accordingly, these shares
(sometimes referred to as "broker non-votes") are considered not entitled to
vote on the non-routine matters.

Abstentions. If you abstain from voting, your shares will nevertheless be
included in the number of shares represented for purposes of determining
whether a quorum is present. Because directors are elected by a plurality of
the votes, an abstention would have no effect on the outcome of the vote on
proposal #1 -- Election of Directors, and thus, is not offered as a voting
option for that proposal. However, abstentions are effectively treated in the
tally of votes against proposal #2.

Tabulation of Votes. ONEOK's transfer agent will be responsible for tabulating
and certifying the votes.

Default Voting. If you properly authorize a proxy electronically via the
Internet, by telephone, or in paper form, but do not indicate any voting
instructions, your shares will be voted as follows:

     .    Proposal 1 -- Election of Directors -- FOR all nominees.
     .    Proposal 2 -- Ratification of the appointment of our principal
          independent auditors for the 2002 Fiscal Year -- FOR.

--------------------------------------------------------------------------------

   3.     Q:  How do I vote?
          A:  You may vote in person at the meeting or appoint a proxy via the
              Internet, by telephone, or by mail to vote your shares. Following
              the Notice of Annual Meeting is a description of the Voting
              Methods available this year. As outlined on Page 1, "Quorum and
              Voting", if you return a signed card but do not provide voting
              instructions, your shares will be voted for the two proposals.

--------------------------------------------------------------------------------

   4.     Q:  How do I revoke my proxy?
          A:  You have the right to revoke your proxy at any time before the
              meeting by:
              (1)  notifying ONEOK's Corporate Secretary in writing;
              (2)  authorizing a different proxy via the Internet;
              (3)  authorizing a different proxy by telephone;

              (5)  voting in person.

                                      -2-



--------------------------------------------------------------------------------

   5.     Q:  Is my vote confidential?
          A:  Proxy cards, ballots and voting tabulations that identify
              individual shareholders are mailed and returned directly to the
              Proxy Tabulator and handled in a manner that protects your voting
              privacy. It is ONEOK's policy to protect the confidentiality of
              shareholder votes throughout the voting process. In this regard,
              the vote of any shareholder will not be disclosed to ONEOK's
              Directors, officers or employees, except:
             .    to meet legal requirements; or
             .    to assert or defend claims for or against ONEOK; or
             .    except in those limited circumstances where
                    (1) a proxy solicitation is contested;
                    (2) a shareholder writes comments on a proxy card; or
                    (3) a shareholder authorizes disclosure.
             Both the tabulators and the inspectors of election have been, and
             will remain, independent of ONEOK. Nothing in this policy
             prohibits shareholders from disclosing the nature of their votes
             to ONEOK's Directors, officers or employees, or impairs voluntary
             communication between ONEOK and its shareholders, nor does this
             policy prevent ONEOK from ascertaining which shareholders have
             voted or from making efforts to encourage shareholders to vote.

--------------------------------------------------------------------------------

   6.     Q:  How is ONEOK, Inc. common stock in the Thrift Plan voted?
          A:  Thrift Plan votes receive the same confidentiality as all other
              shares voted. If you hold shares of ONEOK, Inc. common stock
              through the Thrift Plan, you must instruct the ONEOK, Inc.
              trustee, Bank of Oklahoma, N.A., how to vote your shares. If you
              do not authorize a proxy electronically via the Internet, by
              telephone, or by mail, or if you return it with an unclear voting
              designation, or with no voting designation at all, then the
              trustee will vote the shares in your account in proportion to the
              way the other Thrift Plan participants voted their shares.

--------------------------------------------------------------------------------

   7.     Q:  How will voting on any other business be conducted?
          A:  Although we do not know of any business to be considered at the
              2002 annual meeting other than the proposals described in this
              Proxy Statement, if any other business is properly presented at
              the annual meeting in accordance with Sections 2.11(b) of our
              By-laws, your signed proxy card gives authority to David L. Kyle,
              ONEOK's Chairman of the Board, President, and Chief Executive
              Officer; and John A. Gaberino, Jr., Senior Vice President,
              General Counsel and Corporate Secretary, to vote on these matters
              at their discretion.

--------------------------------------------------------------------------------

   8.     Q:  What shares are included on the proxy card(s)?
          A:  The shares on your proxy card(s) represent ALL of your shares,
              including those in ONEOK's Direct Stock Purchase and Dividend
              Reinvestment Plan and shares held in custody for your account by
              Bank of Oklahoma, N.A., as trustee for the Thrift Plan for
              Employees of ONEOK, Inc. and Subsidiaries. If you do not
              authorize a proxy electronically via the Internet, by telephone,

      Detailed information on each is provided on page 6. The By-laws provide
      that a person cannot be elected or re-elected to the Board after the
      person's 70/th/ birthday. Therefore, effective with this Annual Meeting,
      Mr. Douglas R. Cummings, a Class B director, will no longer be eligible
      to stand for re-election. On February 21, 2002, the Board of Directors
      elected Ms. Pattye L. Moore as a Class B director, and nominated Messrs.
      William M. Bell, John B. Dicus and David L. Kyle and Ms. Pattye L. Moore
      as its nominees for election as Class B directors. It is contemplated
      that at its meeting to be held April 18, 2002, the board will, by
      resolution, reduce the size of the Board from 12 members to 11 members
      due to Mr. Cummings' retirement as of the Annual Meeting. At that time
      the Board will be divided into three Classes (A, B, and C) consisting of
      3 members in Class A, 4 members in Class B and 4 members in Class C. Each
      Class is elected for a term of three years, with the term of one class
      expiring at each annual meeting of shareholders.

     Your Board unanimously recommends a vote FOR each of these directors.

      audit of ONEOK's consolidated financial statements, audits of the
      financial statements of certain ONEOK affiliates, and audits of employee
      benefit plan financial statements. In addition, KPMG provided various
      non-audit services to ONEOK during the 2001 Fiscal Year. See page 12 for
      more details.

      Required Approval -- Approval of this proposal requires the affirmative
      vote of the holders of a majority of the shares of common stock present
      in person or represented by proxy and entitled to vote at the meeting.

      Your Board unanimously recommends a vote FOR the approval of KPMG's

Guidelines and principal functions of the Board are:

    .     Review succession planning and CEO performance evaluation;

    .     Review compensation and stock ownership of the Company's Directors
          and executive officers; and

    .     Review the structure and operations of the Board.

The Board of Directors believes that corporate governance is a continuing
process and these Guidelines are reviewed periodically and may change from time
to time as conditions warrant.

of ONEOK's business objectives, and to align the interests of executive
officers with the long-term interests of ONEOK's shareholders. This Committee
reviews and makes recommendations to the Board on executive and director
compensation, personnel policies, programs and plans. The Executive
Compensation Committee has adopted, and operates under, a charter.

      .    The Nominating and Corporate Governance Committee ensures an
appropriate structure for management succession and development, and an
effective process for director selection and tenure by making recommendations
on the Board's organization and practices and by aiding in identifying and
recruiting director candidates. The Committee also establishes and reviews
issues of corporate governance. The Committee considers nominees recommended by
shareholders for service on the Board of Directors. Recommendations should be

Report of the Audit Committee

The Board of Directors of ONEOK, Inc. (the "Company") adopted a written Audit
Committee Charter in April of 1999. All members of the Audit Committee are
independent as defined in Section 303.01(B)(2)(a) and (3) of the New York Stock
Exchange's listing standards.

The Audit Committee has reviewed and discussed with the Company's management
and KPMG LLP, the Company's independent auditors, the audited financial
statements of the Company contained in the Company's Annual Report on Form 10-K
for the year ended December 31, 2001. The Audit Committee has also discussed
with the Company's independent auditors the matters required to be discussed
pursuant to SAS No. 61 (Codification of Statements on Auditing Standards,
Communication with Audit Committees).

The Audit Committee has received and reviewed the written disclosures letter
from KPMG LLP required by Independence Standards Board Standard No. 1 (titled,
"Independence Discussions with Audit Committees"), and has discussed with KPMG
LLP their independence. The Audit Committee has also considered whether the
provision of information technology services and other non-audit services to
the Company by KPMG LLP is compatible with maintaining their independence.

Based on the review and discussions referred to above, the Audit Committee
recommended to the Board of Directors that the audited financial statements be
included in the Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 2001, filed with the U.S. Securities and Exchange Commission.

Respectfully submitted by the members of the Audit Committee of the Board of
Directors:

         /s/  Gary D. Parker, Chair   /s/  William M. Bell, Vice Chair

         /s/  Edwyna G. Anderson      /s/  John B. Dicus

Directors' compensation

ONEOK annually benchmarks directors' compensation and strives to pay at the
median for companies of comparable size in its industry. A director who is an
officer or employee of ONEOK receives no compensation for his or her services
as a director or as a member of a committee of the Board. A director who is not
an officer or employee receives compensation for his or her services as
described below. All directors are reimbursed for reasonable expenses incurred
in connection with attendance at board and committee meetings.

During Fiscal 2001, eight meetings were held by the Board of Directors. All
directors attended at least seventy-five percent (75%) of the meetings of the
Board of Directors and committees on which such directors served.

The directors' compensation for Fiscal 2001 consisted of: 1) an annual cash
retainer of $22,500; 2) a stock retainer of 400 shares of ONEOK, Inc. common
stock on a post-split basis, the value of which is reflected in the total
directors' fees indicated below; 3) a stock option grant for 10,000 shares of
stock (post-split) granted under the ONEOK, Inc. Non-Employee Directors' Stock
Compensation Plan; and 4) meeting fees of $1,200 per board or committee meeting
attended in person or $600 per board or committee meeting attended via
telephone. Also, each committee chair receives an additional annual cash
retainer of $3,500. The total amount of directors' fees paid in Fiscal 2001 was
$492,311.

In Fiscal 2001, $242,205 of the total amount payable for directors' fees was
deferred under the Deferred Compensation Plan for Non-Employee Directors. All
non-employee directors are eligible to participate in this Plan. In January
each year the non-employee directors may elect to defer all, or a portion of,
the annual cash retainer, the annual stock retainer, and meeting fees payable
by ONEOK. Deferred amounts are treated, at the election of the participating
director, either as phantom stock or as a cash deferral.

Phantom stock deferrals will be treated as though the deferred amount is
invested in ONEOK common stock at the fair market value on the date the stock,
the retainer, and/or fees are earned. Phantom stock earns the equivalent of
dividends, reinvested at the fair market value on the payment date of each
common stock dividend declared. Phantom stock accounts are representative of
shares of common stock which can be issued to a non-employee director under the
ONEOK, Inc. Long-Term Incentive Plan, but are deferred until settlement in
shares of common stock at an elected deferral date. See pages 14-16 for phantom
stock ownership.

Cash deferrals will be credited with interest at the investment return rate
determined by the Executive Compensation Committee.

In January 2000, the Board created a special committee to review issues
relating to the now-terminated agreement to merge with Southwest Gas
Corporation. That committee was chaired by Gary D. Parker, and committee
members were paid the same fee for each meeting as standing committees
received; however, an additional $300 per hour, per director was paid for each

Executive compensation:
Report of the Compensation Committee

The Committee's Responsibilities: The Executive Compensation Committee of the
Board ("the Committee") has responsibility for reviewing, and recommending to
the full Board of Directors, the Company's executive compensation programs to:

..    attract, retain and appropriately reward executive officers;
..    motivate their performance in the achievement of the Company's business
     objectives; and
..    align the interests of executive officers with the long-term interests of
     the Company's shareholders.

The Committee is composed entirely of outside directors. The purpose of this
report is to summarize the philosophical principles, specific program
objectives, and other factors considered by the Committee in reaching its
recommendations regarding the executive compensation of the Named Executive
Officers.

Compensation Philosophy: The Company's executive compensation program is based
on the belief that the interests of executives should be closely aligned with
those of the shareholders. The Committee has adopted a framework of principles
for the management compensation program which:

..    attracts the best talent to ONEOK;
..    encourages executives to manage from the perspective of owners with an
     equity stake in the Company;
..    motivates individuals to perform at their highest levels;
..    encourages strong financial and operational performance of the Company and
     creates shareholder value by maintaining a portion of executives' total
     compensation at risk;
..    rewards outstanding achievement; and
..    retains the leadership and skills necessary for building long-term
     shareholder value.

Compensation Methodology: ONEOK strives to provide a comprehensive executive
compensation program that is competitive and performance-based in order to
attract and retain superior executive talent. Annually, the Committee reviews
market data for two components of executive compensation: (1) annual cash
compensation, and (2) long-term incentive compensation. To assist in
benchmarking the competitiveness of its compensation programs, ONEOK
participates in executive compensation surveys and utilizes independent
compensation consultants. Because the Committee believes that the Company's
direct competition for executive talent is broader than the companies that are
included in the S&P Utilities Index which is used in the Performance Graph on
page 21, the surveys utilized include the American Gas Association Executive
Compensation Survey, the Effective Compensation Oil and Gas Industry
Compensation Survey, the Hewitt Associates Energy Traders Compensation Survey,
the Towers Perrin Compensation Survey of Energy Marketing and Trader Positions,
the Watson Wyatt Worldwide Top Management Compensation Survey, and the William
M. Mercer Finance Accounting and Legal Survey.

Components of Compensation:

..    Annual Cash Compensation: Annual cash compensation for the Named Executive
     Officers, as well as all executive officers, consists of two components,
     base salary and a variable, at-risk incentive.

     Annual base salary is designed to compensate executives for their level of
     responsibility, experience, sustained individual performance, and
     contribution to the Company. The Committee recommends to the Board all
     salary increases for executive officers. The goal is to compensate
     executives at 100% of the competitive base salary levels for similar
     positions by ONEOK's peers as identified through published surveys, company
     documents, and other sources.

     Annual incentive awards are issued under the ONEOK, Inc. Annual Officer
     Incentive Plan (the "Officer Incentive Plan"). The purpose of the Officer
     Incentive Plan is to provide certain officers of ONEOK, Inc. with a direct
     financial interest in the performance and profitability of the Company and
     to reward performance. The Officer Incentive Plan is administered by the
     Committee in accordance with stated purposes and the Committee recommends
     to the full Board of Directors, based on recommendations of the CEO, all
     awards under the Officer Incentive Plan.


                                     -17-



    The Officer Incentive Plan is designed to allow the Company's officers the
    opportunity to earn compensation that is above average when compared to
    ONEOK's peers if ONEOK achieves outstanding results compared to those peers
    and to targeted objectives.

    Incentive criteria are established by the Committee and include achievement
    of certain corporate and unit performance goals as well as individual
    performance criteria as benchmarks for Incentive Awards. Such criteria
    include earnings per share, shareholder appreciation, and return on
    invested capital.

Individual performance criteria includes:


                                                 
   .    problem analysis;                           .    planning and organizational ability;
   .    directing;                                  .    decision-making;
   .    utilization of human, capital & material    .    resoutricmees;management;
   .    initiation of, and response to, change;     .    communication and team relations; and
   .    personal actions.


    The Bonus column of the Summary Compensation Table on page 22 contains the
    annual incentives earned for Fiscal 2001 for each of the Named Executive
    Officers.

..    Long-term Incentive Compensation: On August 20, 1998, the Committee
     recommended to the full Board that it amend and restate the Key Employee
     Stock Plan. The amendments included changing the name to the ONEOK, Inc.
     Long-Term Incentive Plan (the "LTI Plan"), increasing the number of shares
     subject to the LTI Plan, modifying the definition of certain terms
     governing the granting of stock incentives, and providing for payment of
     non-employee director compensation in the form of stock awards. The
     shareholders approved that amendment to the LTI Plan on January 21, 1999.
     On February 15, 2001, the Committee recommended to the full Board that it
     amend and restate the Plan to increase the shares available for issuance.
     That amended and restated Plan was approved by the shareholders on May 17,
     2001, and will remain in effect until all shares authorized to be issued
     as stock incentives have been granted or until the Board terminates the
     LTI Plan. Also on May 17, 2001, the shareholders approved a two-for-one
     stock split, effective June 11, 2001, which had the effect of doubling the
     number of shares available for issuance from the Plan and the outstanding
     options granted.

     The purpose of the LTI Plan is to provide incentives to enable the Company
     to attract, retain, and reward certain employees and to give such employees
     an interest parallel to the interests of the Company's shareholders. The
     LTI Plan is administered by the Committee, and the Committee reviews and
     recommends to the full Board of Directors, after recommendation of the CEO,
     all long-term incentive awards. The Committee is authorized to make all
     decisions and interpretations required to administer and execute the LTI
     Plan. Participation in the LTI Plan is limited to certain employees of
     ONEOK, Inc. who are in a position to contribute significantly to the growth
     and profitability of the Company, its divisions, and subsidiaries.

     The LTI Plan authorizes the Committee to grant stock incentives to eligible
     employees in a variety of forms including: (1) Incentive Stock Options, (2)
     Non-Statutory Stock Options, (3) Restricted Stock Awards, and
     (4) Performance Awards. In 1995, 1996, 1997 and 1998, these awards were
     granted as non-statutory stock options. From 1999 forward these awards were
     granted as non-statutory stock options and/or restricted stock. In
     determining the number of stock options and/or restricted stock awarded,
     the Committee reviewed a survey detailing the 50/th/ percentile of grant
     values of long-term incentives in the general industry, and it also
     considered the participant's past performance. The table below details the
     grants that have been made from the LTI Plan and the balance remaining
     available for grant as of December 31, 2001:

    *    The number of shares listed for grants made through 01/18/01 reflect
         the impact of the 06/11/01 two-for-one stock split.
    **   Restricted stock does not have an expiration date. These shares are
         restricted and vest in full after a three-year period from the date of
         grant. The holders of restricted stock have voting rights for these
         shares and the shares earn dividends.
    ***  This out-of-cycle grant was made to Mr. John W. Gibson upon his
         employment with ONEOK.

         Due to the transition to a December 31/st/ fiscal year end, no options
         or restricted stock were granted in Fiscal 2000 other than the grant
         detailed above for Mr. Gibson.

         Stock Options have an exercise price equal to the fair market value of
         common stock on the date of grant. The options granted in 1995, 1996,
         1997, and in January of 1998 are exercisable beginning one year from
         the date of grant. In 1998 the Committee modified the Non-Statutory
         Stock Option Agreement to allow stock options granted under that
         Agreement to become exercisable beginning one year after the date of
         grant in four equal annual installments.

         Stock Options may include a restoration feature, by which options are
         granted to replace shares that are surrendered by participants as full
         or partial payment to the Company of the purchase price of shares
         being acquired through the exercise of the stock option or shares that
         are surrendered to satisfy the tax obligations incident to the
         exercise of an option. Each restored option shall have an option price
         equal to the fair market value of the Common Stock on the date of
         grant of the restored option and shall expire on the stated expiration
         date of the original option.

         The LTI Plan does not allow for the repricing of stock options.

Chief Executive Officer Compensation: This Committee meets annually to review
the Board of Directors' evaluation of the Chief Executive Officer's ("CEO")
performance. The Committee uses this performance evaluation, the surveys
previously mentioned, and the C.A. Turner Utility Report on financial and stock
performance in considering the CEO's compensation. When reviewing the surveys
and financial data, the Committee factors in that ONEOK's CEO also serves the
Company as Chairman of the Board. Categories in which performance is evaluated
include: (1) leadership, (2) strategic planning, (3) financial issues, (4)
management and operations, (5) human resources, and (6) communications.

   .    Annual Cash Compensation: The Committee recommended, and the Board of
        Directors approved, a base salary amount of $700,000. Mr. Kyle received
        a retroactive salary increase of $82,531, which was earned in Fiscal
        2000 but paid in Fiscal 2001.

        Annual incentive compensation for Mr. Kyle is based on attainment of
        annual performance goals for the Company, and on Mr. Kyle's individual
        objectives and performance as reviewed by the Committee. Based on these
        criteria, Mr. Kyle was awarded $0.00 representing 0% of his
        compensation that related to the Company's performance during the 2001
        fiscal year.

   .    Long-term Incentive Compensation: On January 18, 2001, Mr. Kyle
        received a non-statutory stock option grant of 40,000 shares of stock
        at a purchase price of $44.6250 per share. This grant will become first
        exercisable on January 18, 2002, as to 10,000 shares, and the remaining
        portion of the grant will vest equally over the next three years. Also,
        on January 18, 2001, Mr. Kyle was granted 17,600 shares of restricted
        stock that will vest in full on January 18, 2004.

    The grants made to Mr. Kyle on January 18, 2001 (and all grants issued to
    employees from the ONEOK, Inc. Long-Term Incentive Plan) were impacted by
    the 2-for-1 stock split approved by shareholders at the May 17, 2001,
    Annual Meeting and effective June 11, 2001. After the split, the 01/18/01
    grant for Mr. Kyle resulted in a non-statutory stock option for 80,000
    shares of stock at a purchase price of $22.3125, and a restricted stock
    award for 35,200 shares of stock.

Internal Revenue Service Limitations on Deductibility of Executive
Compensation: In structuring the Company's compensation plans, the Committee
takes into consideration Section 162(m) of the Internal Revenue Code (which
disallows the deduction of compensation in excess of $1,000,000 except for
certain payments based upon performance goals) and other factors the Committee
deems appropriate. As a result, some of the compensation under the Company's
compensation plans may not be deductible under Section 162(m).

Compensation Committee Interlock and Insider Participation: There are none.

Respectfully submitted by the members of the Executive Compensation Committee
of the Board of Directors:

/1/  The restricted stock award values and securities underlying options/SARs
     reflect the impact of the shareholder approved two-for-one stock split
     effective June 11, 2001.
/2/  In 1999 the Company changed its fiscal year end from August 31/st/ to
     December 31/st/. The period shown as SY1999 refers to the four (4) months
     ending December 31, 1999. The period identified as FY1999 refers to the
     fiscal year ended August 31/st/. Therefore, compensation data is presented
     for Fiscal 2001 (ending December 31, 2001), Fiscal 2000 (ending December
     31, 2000), the four-month transition period ended December 31, 1999, and

     participants on a non-preferential basis, and are reinvested in additional
     shares of restricted stock. The values reflected above represent the
     post-split number of shares granted times the post-split grant price of
     $22.3125. Dividends accrued throughout the year and the year-end value of

/6/  ONEOK Texas Resources, Inc., an affiliate of ONEOK, Inc. currently owns
     approximately 11.3% of Magnum Hunter Resources, Inc. Due to Magnum
     Hunter's merger with Prize Energy Corp., which was completed March 15,
     2002, ONEOK Texas Resources, Inc.'s ownership was reduced from
     approximately 22.0% to approximately 11.3% with one director represented
     on the Board. During Fiscal 2001 Messrs. Kyle and Kneale served on the
     Board of Magnum Hunter. The information listed in the table below reflects
     options granted to them as officers of ONEOK serving as Directors of
     Magnum Hunter. The options granted in SY 1999, FY 2000, and FY 2001 were
     granted at exercise prices of $2.50, $7.9375, and $8.44 respectively and
     vested 20% on the date of grant and 20% annually thereafter until fully
     vested. These options have a 10-year term. The option granted to Mr. Kyle
     in FY 1999 was granted upon his election to the Board and vested in full
     upon the date of grant. This option was granted at an exercise price of
     $5.25 and has a 10-year term.

 Notes to option grant table:
/1/  No Stock Appreciation Rights ("SARs") were granted in Fiscal 2001.
/2/  All option grants itemized reflect the impact of the shareholder approved
     two-for-one stock split effective June 11, 2001.
     ONEOK, Inc. options are granted at the Fair Market Value of ONEOK stock on
     the date of grant. The options vest in four-equal annual installments,
     commencing one year from the date of grant. Each option has a 10-year term.
     Although no restored options were granted to the Named Executive Officers
     during Fiscal 2001, the stock option agreements provide that an additional
     option may be granted if, and when, the optionee exercises all or part of
     an option using common stock to pay the purchase price of the option or to
     satisfy tax obligations incident to the exercise of the option. The
     restored option will be exercisable for the number of shares tendered to
     pay the option price or to satisfy any tax obligation, and will be
     exercisable at any time after the expiration of a period of six (6) months
     following the date of grant (or at any other time as determined by ONEOK)
     and will expire on the expiration date of the original grant. Each restored
     option is awarded with an exercise price equal to the fair market value of
     a share of ONEOK, Inc., common stock on the date of the grant.
/3/  These amounts represent assumed rates of appreciation only and are not
     intended to forecast future appreciation of the common stock price. Actual
     gains, if any, on stock option exercises depend on the future performance
     of the common stock and overall market conditions. There can be no
     assurances that the potential values reflected in this table will be
     achieved.
/4/  Currently ONEOK Texas Resources, Inc. owns approximately 11.3% of Magnum
     Hunter Resources, Inc. Due to Magnum Hunter's merger with Prize Energy
     Corp., which was completed on March 15, 2002, ONEOK Texas Resources,
     Inc.'s ownership was reduced from approximately 22.0% to approximately
     11.3% with one director represented on the Board. The table below reflects
     the options granted to Messrs. Kyle and Kneale as officers of ONEOK
     serving as Directors of Magnum Hunter. The options granted in Fiscal Year
     2001 were granted on 12/12/01 at an exercise price of $8.44. These options

Notes to the pension benefits table:

/1/    The Retirement Plan for Employees of ONEOK, Inc. and Subsidiaries is a
       tax-qualified, defined-benefit pension plan under both the Internal
       Revenue Code of 1986, as amended, and the Employee Retirement Income
       Security Act of 1974, as amended. Benefits become vested and
       non-forfeitable after completion of five years of continuous employment.
       A vested participant receives the retirement benefit at retirement age
       under the Retirement Plan, unless an early retirement benefit is elected
       under the Plan, in which case the retirement benefit is actuarially
       reduced for early commencement. Benefits are calculated at retirement
       date based on a participant's credited service, limited to a maximum of
       35 years, and final average earnings. Credited years of service under
       these plans for the Named Executive Officers as of December 31, 2001 are
       as follows: D. L. Kyle, 27 years and 6 months; J. C. Kneale, 20 years
       and 8 months; J. W. Gibson, 1 year and 7 months; J. A. Gaberino, Jr., 3
       years and 11 months; and E. N. Dubay, 5 years and 8 months.

/2/    For purposes of the above table, the annual Social Security Covered
       Compensation benefit ($39,444) was used in the excess benefit
       calculation.

/3/    Under the Internal Revenue Code, the annual compensation of each
       employee to be taken into account under the Retirement Plan for 2001
       cannot exceed $150,000, as adjusted for increases in the cost of living
       for plan years beginning after December 31, 1993. The maximum amount for
       2001, as adjusted, is $170,000.

/4/    Amounts are estimates only and would be subject to adjustment based on
       rules and regulations applicable to the method of distribution and
       survivor benefit options selected by the retiree. The Retirement Plan
       provides that retirement benefits would be actuarially reduced for
       retirement prior to age 65.

/5/    The compensation covered by the Retirement Plan benefit formula is the
       basic salary paid to an employee within the employee's final average
       earnings. The final average earnings means the employee's highest
       earnings during any sixty consecutive months during the last 120 months
       of employment. For any employee named or shown in the Summary
       compensation table who retires with vested benefits under the Plan, the
       compensation shown as "salary" in the Summary compensation table could
       be considered covered compensation in determining benefits, except that
       the Plan benefit formula takes into account only a fixed percentage of
       final average earnings which is uniformly applied to all employees. The
       amount of covered compensation that may be considered in calculating
       retirement benefits is also subject to limitations in the Internal
       Revenue Code of 1986, as amended, applicable to the Plan.

The following table sets forth the estimated benefits payable upon retirement

The SERP covers certain elected or appointed officers of ONEOK, and certain
other employees in a select group of management and highly compensated
employees of ONEOK. Participants are selected by the CEO, or in the case of the
CEO, by the Board of Directors.

Benefits payable to participating employees under the SERP are based upon a
specified percentage (reduced for early retirement) of the highest 36
consecutive months' compensation of the employee's last 60 months of service.

The SERP will, in any case, pay a benefit equal to the benefit which would be
payable to the participant under the Retirement Plan if the limitations imposed
by the Internal Revenue Code Sections 401(a)(17) and 415(b) were not
applicable, less the benefit payable under the Retirement Plan with such
limitations. Benefits under the SERP are paid coincidentally with the payment
of benefits under the Retirement Plan or as the administrative committee may
determine. SERP benefits are offset by benefits payable under the Retirement
Plan.

ONEOK provides for funding of this benefit through a trust arrangement commonly
referred to as a Rabbi Trust.

The Board of Directors may amend or terminate the SERP at any time; however,
benefits to current participants may not be reduced.

Change in control and termination agreements

During 2001, ONEOK, Inc. amended its termination agreements with each of its
named executive officers to standardize the change in control provisions with
ONEOK's other documents. Each of the termination agreements has a three-year
term, but will be extended automatically in one-year increments after
expiration of the initial three-year term unless ONEOK provides notice to the
officer at least 90 days before the January 1 preceding the initial termination
date of the agreement that it does not wish to extend the term.

Under the termination agreements, severance payments and benefits are payable
if there is a change in control of ONEOK and the officer's employment is
terminated without "just cause" or for "good reason" at any time during the
three years after the change in control, or for Mr. Kyle, for any reason by the
executive within twelve months of the change in control. In general, these
severance benefits include:

..     a lump sum payment in an amount equal to three times the officer's then
      current annual compensation, plus a prorated portion of the officer's
      short-term incentive compensation;
..     accelerated vesting of retirement and other benefits under ONEOK's SERP;
..     continuation of welfare benefits for thirty-six (36) months;
..     for Mr. Kyle, gross up payments to cover any excise taxes due if any
      portion of his severance payments constitute excess parachute payments;
      and
..     for each of the other named executive officers, severance payments will
      be reduced if the net after-tax benefit to such named executive officer
      exceeds the net after-tax benefit if such reduction were not made. ONEOK
      will make gross up payments to such officers only if the severance
      payments, as reduced, constitute excess parachute payments.

Calculated using base salary and bonus levels during 2001, and assuming a
December 31, 2001, change in control and termination date, payments under the
termination agreements (excluding any gross up payments) with ONEOK's named
executive officers would have been: D. L. Kyle, $6,864,888; J. C. Kneale,
$2,847,044; J. W. Gibson, $2,212,710; J. A. Gaberino, Jr., $1,837,685; and E.
N. Dubay, $1,849,243.

Under each termination agreement, a change in control will occur upon:

..     The acquisition by any "person" of beneficial ownership of 20% or more of
      the outstanding voting securities of ONEOK, except (1) voting securities
      acquired in a "non-control acquisition," including an employee benefit
      plan maintained by ONEOK or one if its direct or indirect majority-owned
      subsidiaries or affiliates (a "related person"); (2) ONEOK or a related
      person; or (3) voting securities acquired by any person in a "non-control
      transaction" (defined below);
..     A change in the composition of ONEOK's board of directors as of 02/15/01
      and any additional directors approved by a vote of at least two-thirds of
      the incumbent board, after which the incumbent directors (or their
      designees) no longer constitute at least a majority of the members of the
      board of directors of ONEOK or any parent corporation that results from a
      merger;
..     The consummation of a merger, consolidation or reorganization with or
      into ONEOK or in which securities of ONEOK are issued (a "merger"),
      except mergers that are a non-control transaction. A "non-control
      transaction" occurs when (1) immediately after the merger, ONEOK's
      stockholders beneficially own at least 50% of the outstanding voting
      securities of the surviving entity or its parent; as long as no other
      third party beneficially owns 50% of the outstanding voting securities of
      the surviving corporation; (2) ONEOK's incumbent directors before the
      merger constitute at least a majority of the board of the surviving
      entity or its parent; and (3) no person, other than (a) ONEOK or its
      related persons, (b) an employee benefit plan maintained by ONEOK or its
      related persons, or (c) any person who, immediately before the merger,
      owned 30% or more of ONEOK's outstanding voting securities, has
      beneficial ownership of 30% or more of the outstanding voting securities
      of the surviving entity or its parent;
..     A complete liquidation or dissolution of ONEOK; or
..     The sale or other disposition of all or substantially all of ONEOK's
      assets to any person, except (1) transfers to a related person; (2)
      transfers under conditions that would constitute a non-control
      transaction, with the disposition of assets being regarded as a merger
      for this purpose; and (3) the distribution to ONEOK's stockholders of the
      stock of a related person or any other assets.

                                     -28-



Special Exceptions.  Acquisitions of ONEOK voting securities over the 20%
threshold by any person will not trigger a change in control if:

..     the acquisition occurs as a result of the acquisition of voting
      securities by ONEOK that reduces the total number of shares then
      outstanding and increases the proportional number of shares beneficially
      owned by each shareholder (e.g., a stock buyback program);
..     within five business days after a change in control would have occurred,
      the shareholder who has acquired 20% or more of ONEOK's voting securities
      divests itself of sufficient shares to fall below 20%; or
..     after a person discovers or is notified by ONEOK that its acquisition of
      shares would have triggered a change in control, the person notifies the
      board of directors that it acquired the shares inadvertently, and within
      two business days after such notification, the person divests itself of a
      sufficient number of shares to fall below 20%.

Western Resources Exceptions.  A change in control will not occur if:

..     Western Resources and/or its affiliates (the "shareholder group") acquire
      beneficial ownership of 15% or more of ONEOK's voting securities under
      the terms of the Shareholder Agreement, until the earlier of (a) the
      termination of the Shareholder Agreement or (b) the successful
      consummation of a Buyout Tender Offer as defined in Section 3.6(b) of the
      Shareholder Agreement; or
..     the equity securities of ONEOK owned by the shareholder group are
      restructured with the approval of a majority of the members of ONEOK's
      existing board (excluding nominees of Western Resources).

                                     -29-



Section 16(a) beneficial ownership reporting compliance

ONEOK believes that during Fiscal 2001 all Securities and Exchange Commission
filings of its officers, directors and ten percent shareholders complied with
the requirements of Section 16 of the Securities Exchange Act, based on a
review of forms filed, or written notice that no annual forms were required.

Other matters

We do not know of other matters that are likely to be brought before the
meeting.
